中国正在快速城市化。 1996年中国城市人口为总人口的 30 %。根据预测 ,到2 0 10年 ,城市人口将增长到全国总人口的 45 %。中国和日本等国家历史上发生的强烈地震经验一再表明 ,现有的现代化的城市 ,虽然从表面上看 ,有先进技术作保证 ,但实际上对破坏性地震却是非常脆弱的。本文在阐述转变减轻城市地震灾害观念的基础上 ,根据我国和日本等其他国家近年来发生的灾害性地震的经验教训和工程实践 ,对面向 2 1世纪减轻城市地区地震灾害急需开展研究的课题作了论述。
China is rapidly urbanizing. In 1996, China’s urban population was 30% of the total population. It is projected that by 2010 the urban population will grow to 45% of the country’s total population. The strong earthquake experience in the history of countries such as China and Japan has repeatedly shown that the existing modernized cities are superficially vulnerable to devastating earthquakes, although they are guaranteed by advanced technologies. Based on the experience of changing the concept of mitigation of urban earthquake disaster and the experiences and lessons of engineering and other disastrous earthquakes in other countries such as Japan and Japan in recent years, this paper analyzes the urgent need to study the mitigation of urban earthquake disaster in the 21st century The discussion.
